Device for suctioning

ABSTRACT

The suction device has a telescoping upper and lower casing and an interposed carrier director with fixtures attached for the purpose of controlling suction and the amounts of fluid allowed into the lower casing of the instrument, and depending on the controlled protrusion of the carrier-director, control of suction and fluid in the parts to be suctioned is obtained, as well as releasing unwanted parts that may be suctioned into the mouth of the instrument. Transmission of pressure to the carrier-director directly by pushing a knob on the proximal end of the carrierdirector or indirectly by pushing the upper casing which telescopes over the lower casing moves the carrier director by transmitting pressure over fixtures enclosing a spring on the carrier-director. A ring on the distal end of the carrierdirector is moved to slide over the u fluid inlet in the distal portion of the lower casing, thus stopping the flow into and out of the mouth of the lower casing, while a ball-like object attached to the lower end of the carrier-director is protruded away from the mouth of the lower casing thus allowing the transmission of suction to the parts suctioned. If unwanted parts are inadvertently suctioned to the opening of the lower casing, further protrusion of the carrier-director by direct pressure on the knob of the carrier-director moves the ring away from the fluid inlet, permitting fluid to enter the lower casing and flush the intruding portion away from the mouth of the device. Release of pressure on the carrier-director knob allows the continuation of suctioning of the body parts intended. Release of the upper casing closes off the device from the body and permits the inflow of fluid into the lower casing and continuation of suctioning of the matter taken into the device. Thus the suctioned matter is diluted and pressured out of the suction outlet on the upper part of the lower casing by the fluid. The spring tension having been released by release of pressure on the upper casing retracts the carrier-director and the attached ring and ball move away from the fluid inlet, respectively, and the ball occludes the mouth of the lower end of the device, thus continuous suction and dilution occur in the lower casing which has been closed off from the body parts.

Rosenbaum [57] ABSTRACT The suction device has a telescoping upper and lower casing and an interposed carrier director with fixtures attached for the purpose of controlling suction and the amounts of fluid allowed into the lower casing of the instrument, and depending on the controlled protrusion of the carrier-director, control of suction and fluid in the parts to be suctioned is obtained, as well as releasing unwanted parts that may be suctioned into the mouth of the instrument. Transmission of pressure to the carrier'director directly by pushing a knob on the proximal end of the carrierdirector or indirectly by pushing the upper casing which telescopes over the lower casing moves the carrier director by transmitting pressure over fixtures enclosing a spring on the carrier-director. A ring on the distal end of the carrier-director is moved to slide over the u fluid inlet in the distal portion of the lower casing, thus stopping the flow into and out of the mouth of the lower casing, while a ball-like object attached to the lower end of the carrierdirector is protruded away from the mouth of the lower casing thus allowing the transmission of suction to the parts suctioned.

If unwanted parts are inadvertently suctioned to the opening of the lower casing, further protrusion of the carrier-director by direct pressure on the knob of the carrier-director moves the ring away from the fluid inlet, permitting fluid to enter the lower casing and flush the intruding portion away from the mouth of the device. Release of pressure on the carrierdirector knob allows the continuation of suctioning of the body parts intended, Release of the upper casing closes off the device from the body and permits the inflow of fluid into the lower casing and continuation of suctioning of the matter taken into the device. Thus the suctioned matter is diluted and pressured out of the suction outlet on the upper part of the lower casing by the fluid. The spring tension having been released by release of pressure on the upper casing retracts the carrier-director and the attached ring and ball move away from the fluid inlet, respectively, and the ball occludes the mouth of the lower end of the device, thus continuous suction and dilution occur in the lower casing which has been closed off from the body parts.

7 Claims, 3 Drawing Figures DEVICE ron SUCTIONING Field of Invention The invention relates to suction devices and particularly to suction devices used in surgery. In decompressing obstructed intestines by direct intervention into the lumen of the intestine from without, an instrument is needed which will not be obstructed by the suctioned material, and which will not engage vital material or parts not desired into the instrument. The same qualities are needed in the suction applied to body cavities, as the pelvis, abdomen or thorax. Conventional suction devices used in surgery do not have the means to accomplish these ends.

BRIEF SUMMARY OF THE INVENTION The chief fault of ordinary suction devices is that they become clogged and thereby endanger the patients life by allowing spillage and contamination of infected fluids such as occurs in cases of intestinal obstruction. The prevention of clogging of the device is accomplished by suctioning titred amounts of material into the lower casing whereupon the matter is diluted by an influx of fluid admitted into the device through a fluid inlet which is covered by a ring attached to a carrier-director only when the telescoping upper casing is depressed to the stop position accomplished by a fixture on the lower casing to arrest the descent of the upper casing. The distance of this traverse of the upper casing is determined by the amount of protrusion of the bell-like fixture at the end of the carrier-director which optimally keeps the walls of the suctioned intestine from being drawn into the month of the lower casing. If unwanted structures were to intrude into the mouth of the device they may be released by a further depression of the carrier-director which carries the obstructing ring away from the opening of the fluid inlet and allows a flush of fluid to help remove the intrusion. The ball-like object at the end of the carrier is nontraumatic to delicate structures as it pushes against structures in a gliding fashion and meets structures with a smooth surface in a tangential direction. The fixtures are as follows, the casings telescope with an interposed carrier-director which holds a spring under tension between an upper or proximal fixture which is disclike and the upper wall of the lower casing. Immediately beneath the upper wall of the lower casing is another disk attached to the carrier-director which prevents distraction of and assures return to release position of the carrier-director when the spring is released by release of the depressed upper casing. The cycle is completed by uncovering of the fluid inlet when the carrier director moves the ring wall attached 'to the carrier away from the inlet. Fluid automatically enters and helps dilute and pressure the fluid out of the suction outlet tube at the upper end of the lower casing and the ball occludes the mouth of the lower casing, thus shutting off suction from the intestine but the suction continues to remove the matter in the lower casing. The drawings and the detailed description which follow are intended to illustrate the general principles of the invention, but no limiting sense is intended since the scope of the invention is best defined by the appended claims.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a cross section showing the device in position I. FIG. 2 is a cross section showing the device in position II. FIG. 3 shows a cross section of the device in position III.

DETAILED DESCRIPTION The actual operation of the instrument sequentially is best explained by starting with position II shown in FIG. 2. This shows the device with the ball 13, in a position which is protruded away from the mouth, 14, of the lower casing, 16, so that matter to be suctioned say from the small intestine, gains access to the device because of the suction which is applied to the outlet, 2, which suction is transmitted to the small intestinal contents or to some body cavity. In this position fluid from the inlet. 4, cannot enter the lower casing, 16, because a ring, 12, which is hollow occludes the inlet, 4, by the wall of the ring being in apposition with the inlet 4. The ring is fixed to the carrier-director rod, 18. The smooth ball, 13, attached to the rod, 18, avoids trauma to the delicate structures by tangential contact, and in thecase of the opened and suctioned'intestine, protrudes to a distance which is optimal for keeping the wall of the intestine from being sucked into the mouth 14, of the lower casing, 16. It is this distance of optimal protrusion which determines the distances of the ring like obstacle, 7, on the upper portion of the lower casing from the upper casings lower edge in FIG. I and the same distance determines how far the hollow ring, 12, on the carrierdirector, 18, is above the inlet, 4, in FIG. ll. FIG. 2 shows the carrier-director, 18, with the attached ring, 12, and ball, 13, is protruded to this position by pressing the upper casing, 6, to the arrested position against the fixture, 7. The disc, 8, attached to the carrier-director, 18, in turn is pressed against by the upper casing, 6, which slides on the rod, 18, by reason of a hole in the upper casing wall, and pressing the fixed disc, 8, on the rod, 18, compresses a spring, 10, which lies free between the disc 8 and the upper wall of the lower casing, and is sur rounded by the upper casing, 6. Another fixture, l, of disclike nature is fixed to the carrier-director, 18, and this disc is arrested against the under surface of the "upper part of the lower casing, 16, When the pressure which depresses the carrierdirector, 18, is removed, as in position shown in FIG. 1. In FIG. 2, the disc, 1, moves as the carrier-director moves.

The position I shown in FIG. 1, is attained by release of pressure over the upper casing shown depressed in FIG. 2. The ring 12 affixed to the carrier-director is moved proximally to the fluid inlet, 4, allowing access of fluid into the lower casing, 16, which casing is also closed off from the part of the body which was suctioned, because the ball, 13, affixed to the end of the carrier-director, 18, is carried up to occlude the mouth, 14, of the lower casing, 16. The fluid let in continuously in FIG. I, dilutes and pressures the suctioned matter in the lower casing, 16, out of the suction outlet, 2, on the upper end of the lower casing, 16.

The position III shown in FIG. 3, follows FIG. 2, by further depressing the carrier-director, 18, through pressure on the knob, 5, on the upper end of the carrier-director rod, 18. This position carries the hollow ring 12, away from the fluid inlet, 4. Thus a flush of fluid would disengage any unwanted structure that might have intruded into the mouth of the device. Protrusion of the carrier-director shown in FIG. 3, occurs to a distance depending on the full compression of the spring, 10, against the upper wall of the lower casing, 16, by the disc, 8, affixed to the carrier-director, 18. Release of the pressure over the carrier, 18, allows the carrier to netum to that shown in position I of FIG. 2, since the released spring drives the affixed disc 8, against the under surface of the upper part of the upper casing, 6.
